R help - Dec 2011 - PCA in r

Hello
Would anyone be able to direct me to information on how to perform a
straightforward Principal Components Analysis in r?  Including the data file
set-up? 

I'm rather new to r and not having much luck.
I'm pretty certain I have the data entered into the txt file properly but
when I try to follow some of the examples online I receive a number of errors in
r that I don't understand.
Any help would be greatly appreciated.
thanks
Mark

You'll get more useful answers if you tell us what you did, and provide a
reproducible example.

For instance, a bit of your data using dput(), your sessionInfo(), str() for
your data, and the actual commands you're using to run PCA, as well
as the error messages you're getting.

The clearer you are, the easier it is to solve your problem. The posting
guide has good suggestions.
